Abstract

PURPOSE:To realize a digital telephone set with high convenience by providing a confirming means for the presence/absence state of a user and controlling the actuation of a call control means according to whether the user is present or not. CONSTITUTION:When there is an incoming signal, an interface circuit 2 reports the incoming to the processor 131 of an input/output signal control part 13 and an incoming operation is started. The processor 131 of the input/output signal control part 13 receives a presence/absence confirmation signal which is outputted by a presence/ absence confirmation sensor 19 and digitized by a presence/absence confirmation sensor interface circuit 20 through an input/output control circuit 134 and discriminates whether the user is present or not. A call signal and a ring-back tone control signal are outputted to a calling circuit 18 through the input/output control circuit 134, so that a sounder 17 sounds with sound volume corresponding to the preset position of a sound volume changeover switch 23 and tone corresponding to the preset position of a tone changeover switch 24. When the user's absence is discriminated, the processor 131 of the control part 13 outputs the call signal and ring-back tone control signal through the control circuit 134 to make the sounder 17 to sound with a little bit larger sound volume and moderate tone.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone set having a function of confirming the presence of a user and a function of detecting and determining the brightness and darkness of the usage environment or the noise level.

[Conventional technology]

Against the background of the need for more sophisticated telephone services,
In addition to the basic functions of a telephone for incoming and outgoing calls, it has advanced functions such as an automatic redial function, a ringtone volume adjustment and tone switching function, a function to automatically make a call at a specified time, and a dial illumination function for dialing at night. One-talk terminals have been put into practical use.

However, in those traditional phones, each function launches.

Since all controls such as setting, canceling, and stopping are dependent on the user's manual key operations, there are the following inconveniences.

[Problems to be solved by the invention] fil 7 The volume of the ringer that notifies the user of an incoming call is set depending on when the user uses the telephone nearby, for example, but not at the desk. When you leave your seat or are away, the ringer volume is too low. Moreover, this is especially true when the ambient noise is high. In recent years, telephones that can change the volume and tone of the ringtone have been put into practical use, but when the user is near the telephone, the volume can be set to the desired volume, but when the user is away from the telephone, , the ringing volume may be too low.

(2) If the user becomes absent while in the automatic recall state or automatic recall standby state, a call is made with the caller absent.

(3) When making a call at a specified time, if the user is absent at the specified time, the call will be made with one caller absent, as in (2).

(4) At night, it is desirable that the volume of the ringer be kept to a minimum, but there is no difference between day and night (high volume of the ringer makes people around you feel uncomfortable).

(5) Since the dial illumination is done manually, it is first necessary to find the installation location of the telephone and the dial illumination key in the dark. Also, as a measure against the problem 7, it may be possible to turn on the dial illumination all the time, but this is not preferable as it would be a waste of energy.

(6) The appropriate listening volume during a call varies depending on the level of ambient noise, but the listening volume of conventional telephones is constant, making it difficult to hear in places with large ambient noise.

In recent years, telephones with volume controls for adjusting the volume of incoming calls have been put into practical use, but the user must manually adjust the volume according to the surrounding noise.

accompanied by annoyance.

(7) In recent years, there are electronic telephones that include a volume control circuit that adjusts the volume of a speaker that emits ringtones and hold alarm sounds according to the output of an infrared detection device (Japanese Patent Laid-Open No. 60-418
Publication No. 48 β), automatic repeat calls, calls made at specified times, etc. are not used for control of making and receiving calls, and the inconveniences mentioned in (1) and (3) above have not been improved. .

This invention is highly convenient because it solves the inconvenience of controlling outgoing calls regardless of the presence of the user, brightness, ambient noise level, etc. The purpose is to provide a talking machine. - [Means for solving the problem] The first invention according to the present invention is an existence/nonexistence confirmation means for confirming the presence of a user, and an input/output device for controlling activation of a call control means using the presence/absence confirmation means. It is equipped with a signal control means.

The second invention according to the present invention includes activation control of a presence/absence confirmation means for confirming the presence of a user, a light/darkness detection means, an illumination means, and a call control means.

It is equipped with input/output signal control means for starting or stopping the lighting means, controlling the calling means, etc.

Furthermore, the third invention according to the present invention provides activation control of a presence/absence confirmation means for confirming the presence of a user, a noise level detection means, and a call control means.

and input/output signal control means for controlling activation of the calling means.

[Effect]

In the first aspect of the present invention, the presence/absence confirmation means confirms the existence of the re-user and then activates the call control means.

In addition to the effects of the first invention, the second invention of the present invention provides a work input to the illumination means when the light/darkness detection means determines that the darkness around the filling machine is below a predetermined level. Provide background lighting for the means.

Furthermore, in addition to the effects of the first invention, the third aspect of the present invention controls activation of the calling means in accordance with the degree of noise around the telephone detected by the noise level detection means.

The processor 131 of the input/output signal control unit 13 receives the presence confirmation signal outputted from the presence confirmation sensor 19 via the input/output control circuit 134 and digitized by the presence confirmation sensor interface circuit 20, and receives the presence confirmation signal from the user. Identify presence (2). Step (When it is determined that 21Vc is present, the processor 131 of the input/output signal control unit 13 calls the calling circuit 1BVC via the input/output control circuit &8134.
A ringing signal and a ringing tone control signal are output, and the volume is set in advance according to the position of the volume changeover switch 23.

and make the Sawanda 17 sound with a tone that matches the position of the tone changeover switch 24 that has been set in advance (3) e
When it is determined that the person is absent in step (2), the processor 131 of the input/output signal control unit 13 outputs a ringing signal and a ringing tone control signal to the calling circuit 18 via the input/output control circuit 134, Sound the Sawanda 17 with a gentle tone (4). Step (
31, f4) when the user goes off-hook due to the ringing of the sakunda 11 (5).

The processor 131 of the input/output signal control section 13 stops outputting the calling signal from the input/output control circuit 134, stops the ringing of the sakunda 17 (6), and shifts to the state H in which 9 calls are in progress (7). When the user ends the call and goes off-hook (8
), the processor 131 of the input/output signal control unit 13 ends the blasphemy. Step (If the user does not go off-hook at VC 51, the processor 13 of the input/output signal control unit 13
1 checks whether there is a disconnection instruction from the 1st station line 10 via the interface circuit 12 (9), and if there is a disconnection instruction, stops the output of the call signal from the input/output control circuit 134 and stops the ringing of the Sawanda 17. (10) Step (
If there is no cutting instruction in step (9), the process returns to step (5). The operations after step (5) are as described above.

Next, Fig. 1 and Fig. 2 explain the operation when making a call.

This will be explained using Table 1 and the flowchart in FIG. Note that (11) to (34) in FIG. 4 indicate each step.◎ When the user goes off-hook to make a call (II), the processor 131 of the input/output signal control s13 receives input from the group of oysters 16 entering the user's car. The dialed number is detected, stored in the data memory 133, and sent to the station [10] via the interface circuit 12 (12). After seven
The processor 131 of the human output signal control unit 13 waits for an incoming response signal from the 1-station line 10 via the interface circuit 12, and when there is an incoming response signal (1, call busy status?il) (25). .When the user ends the call and hooks Eon, <y,), the outgoing call ends. In step (13), when the user goes on-hook because there is no incoming response signal (
14), the processor 131 of the input/output signal control unit 13,
Check whether the user has input the automatic recall key from the input key group 16 via the input/output control circuit 134 (15);
If this input is received, a timer for automatic recalling is started (16). Processor 13 of input/output signal control section 13
1 monitors whether or not the automatic recall interval has elapsed 17), and when the automatic recall interval has elapsed, the work status confirmation sensor 19 outputs an output via the input/output control circuit 134,
The device receives the presence/absence confirmation signal converted into a digital form by the presence confirmation sensor interface circuit 20 and identifies the presence/absence of the user.

When it is determined that the speaker 711V is present in step (18), the processor 131 of the input/output signal control unit 13
From C, the state changes to the speaker listening state where only the call can be received and no calls can be made, and 1 automatically makes a call (19).At the same time, in step (x2), the dial number stored in Vc is read from the data memory 133, and the interface circuit 12 is activated. The data is transmitted to the central office line 10 (20).

Thereafter, the processor 1 of the input/output signal control unit 13 immediately
31 is a timer t for the time to continue calling after the first automatic repeat call.
(21), and while the call continues, check whether there is an incoming response from the central office line 10 via the interface circuit 12 (e2), and if there is an incoming response, stop the timer t, and then Q3
), the call becomes a loudspeaker call (24), and the state shifts to a call-in-progress state (05) e Step (25) and subsequent operations are the same as described above.

Step (If there is no response from the first call after two calls, the processor 131 of the input/output signal control unit 13 checks whether the timer t2 has exceeded the time for one automatic call to continue calling (27).
), if it exceeds, after stopping timer t1 (28)
29), the process returns to step (16), starts the timer t1 again, and continues automatic recall. The processor 131 of the human output signal control section 13 controls the input/output control circuit 1
The system monitors whether or not the user manually presses the automatic repeat stop key from the input key group 16 via step 4. If there is an input, after stopping the speaker reception (step 31), the timer t2 is stopped and the automatic Recall ends (32nd).

If the automatic recall stop key is not input at step (30), the process returns to step (22) and automatic recall is continued. If the user is absent at step (18), automatic recall is terminated.Step ( 17) At timer t1
The pulse processor 131 of the input/output signal control unit 13 is configured to input an automatic recall stop key from the input key group 16 via the input/output control circuit 134 until the automatic recall is performed. 33), and if there is an input, the automatic recall is terminated (34).
